Differences in medication reconciliation interventions between six hospitals: a mixed method study.

BACKGROUND: Although medication reconciliation (MedRec) is mandated and effective in decreasing preventable medication errors during transition of care, hospitals implement MedRec differently. OBJECTIVE: Quantitatively compare the number and type of MedRec interventions between hospitals upon admission and discharge, followed by a qualitative analysis on potential reasons for differences. METHODS: This explanatory retrospective mixed-method study consisted of a quantitative and a qualitative part. Patients from six hospitals and six different wards i.e. orthopaedics, surgery, pulmonary diseases, internal medicine, cardiology and gastroenterology were included. At these wards, MedRec was implemented both on hospital admission and discharge. The number of pharmacy interventions was collected and classified in two subcategories. First, the number of interventions to resolve unintended discrepancies (elimination of differences between listed medication and the patient's actual medication use). And second, the number of medication optimizations (optimization of pharmacotherapy e.g. eliminating double medication). Based on these quantitative results and interviews, a focus group was performed to give insight in local MedRec processes to address differences in context between hospitals. Descriptive analysis (quantitative) and content analysis (qualitative) was used. RESULTS: On admission 765 (85%) patients from six hospitals, received MedRec by trained nurses, pharmacy technicians, pharmaceutical consultants or pharmacists. Of those, 36-95% (mean per patient 2.2 (SD ± 2.4)) had at least one discrepancy. Upon discharge, these numbers were among 632 (70%) of patients, 5-28% (mean per patient 0.7 (SD 1.2)). Optimizations in pharmacotherapy were implemented for 2% (0.4-3.7 interventions per patient upon admission) to 95% (0.1-1.7 interventions per patient upon discharge) of patients. The main themes explaining differences in numbers of interventions were patient-mix, the type of healthcare professionals involved, where and when patient interviews for MedRec were performed and finally, embedding and extent of medication optimization. CONCLUSIONS: Hospitals differed greatly in the number of interventions performed during MedRec. Differences in execution of MedRec and local context determines the number of interventions. This study can support hospitals who want to optimize MedRec processes.

Key factors underlying the willingness of patients with cancer to participate in medication redispensing.

BACKGROUND: Redispensing medication unused by patients to other patients could reduce the environmental burden of medication waste. Simultaneously, associated financial loss could be reduced, particularly for expensive medication such as oral anticancer drugs. An important determinant for successful medication redispensing is patient participation. OBJECTIVE(S): To identify key factors underlying the willingness of patients with cancer to participate in the redispensing of unused oral anticancer drugs. METHODS: Semi-structured interviews via telephone or video call were conducted with adult patients diagnosed with cancer from two Dutch hospitals. The interview guide was framed using the COM-B model for behavioural change, to elicit patients' capability, opportunity and motivation to participate in medication redispensing. Questions were related to patients' willingness to accept redispensed medication, reasons thereof, perceived concerns and needs. Inductive thematic analysis was applied. RESULTS: Seventeen patients (aged 38-82 years, 71% female), with nine different types of cancer participated. The majority of participants supported medication redispensing. Four categories of key factors underlying the willingness of patients with cancer to participate in medication redispensing were identified. First, the driver for participation was having positive societal impact, relating to affordability and sustainability of healthcare. Second, having trust in product quality was a requirement, influenced by preconceived beliefs, quality assurance and patients' knowledge of this process. Third, a facilitator for participating in medication redispensing was adequate provision of information. This concerned awareness of medication waste, information about medication redispensing, support from healthcare providers and other patients, and insight into medication dispensing history. Last, a convenient process for returning unused medication to pharmacies would facilitate participation in medication redispensing. CONCLUSIONS: The willingness of patients with cancer to participate in medication redispensing relates to a drive for achieving positive societal impact, provided that medication is of high quality, there is adequate information provision and a convenient process.

A pilot study examining patient preference and satisfaction for ava®, a reusable electronic injection device to administer certolizumab pegol.

Background: Anti-tumor necrosis factor (anti-TNF) adherence is suboptimal. ava®, a reusable electromechanical self-injection device (e-Device) developed for certolizumab pegol (CZP) administration, aims to overcome some barriers to increase adherence. This study evaluates patient experience of the e-Device and its training materials and determines patient device preference.Methods: CZP-treated patients were recruited from the Netherlands, Denmark and Sweden. Patients completed a pre-injection Assessment of Self-Injection (ASI) questionnaire investigating self-injection perception. After training, patients administered 3 consecutive self-injections using the e-Device, patient experience of each was assessed using the post-injection ASI. An additional questionnaire evaluated training materials. After Injection 3, patients indicated their preference: the e-Device or their previous device.Results: 59 patients participated; most rated the e-Device highly for satisfaction, self-confidence and ease of use. The (negative) feelings and pain and skin reactions domains had low ratings. Post-injection ASI domain scores were similar following each of the 3 e-Device injections. Training materials were rated highly (video: 8.4/10; step-by-step guide: 8.4/10). 57.1% (32/56) patients preferred the e-Device over their previous self-injection device.Conclusions: Patients were satisfied with the e-Device and most preferred it over other self-injection devices. By improving patient experience, the e-Device may help increase medication adherence.

Quantity and economic value of unused oral anti-cancer and biological disease-modifying anti-rheumatic drugs among outpatient pharmacy patients who discontinue therapy.

BACKGROUND: Patients sometimes discontinue the use of expensive oral anti-cancer drug (OACD) or biological disease-modifying anti-rheumatic drug (bDMARD) therapies early, leading to medication waste if the patient has not used all dispensed medication. OBJECTIVE: To determine the proportion of patients who have unused OACDs or bDMARDs after therapy discontinuation, and the quantity and economic value of these unused medications. Furthermore, patients' reasons for therapy discontinuation and their disposal method for unused medications were determined. METHODS: In a retrospective follow-up study using a Dutch outpatient pharmacy database, patients (≥18 years) who did not refill an OACD or bDMARD prescription, dispensed between November 2015 and February 2016, within two weeks of the prescription end date were contacted by phone and asked about their unused medication and reasons thereof. The economic value was calculated using Dutch medication prices. Data were descriptively analyzed in STATA13. RESULTS: The database included 1173 patients, of whom 159 likely had discontinued therapy and were contacted. Of these, 88 patients were excluded (39 refilled, 47 missing, and 2 other). Of the 71 patients who had discontinued therapy, 39 (54.9%) had unused medications, comprising 22 OACD users (mean age 63.0 (SD ±â€¯15.9) years, 50.0% female) and 17 bDMARD users (mean age 50.7 (SD ±â€¯13.5) years, 47.1% female). A total of 59 packages were unused, with a total value of €60,341. Unused OACD packages and bDMARD packages had median values of €179 (IQR €24-2487) and €992 (IQR €681-1093), respectively. Patients primarily discontinued therapy due to adverse or insufficient effects. CONCLUSIONS: This study illustrates that more than half of patients discontinuing OACD or bDMARD therapies have unused medication. This emphasizes the need for waste-reducing interventions.

The Impact of Inadequate Temperature Storage Conditions on Aggregate and Particle Formation in Drugs Containing Tumor Necrosis Factor-Alpha Inhibitors.

PURPOSE: To measure aggregate and particle formation in tumor necrosis factor-alpha (TNF-α) inhibitors etanercept, adalimumab and certolizumab pegol product samples after exposure to freezing temperature conditions similar to storage conditions previously observed in patients' homes. METHODS: TNF-α inhibitors in their original primary and secondary packaging were exposed to 32 freeze-thaw cycles (-10°C for 120min/5°C for 60 min) or continuous low storage temperature (-20°C for 96 h) before thawing at 2-8°C. Non-stressed products were used as controls. The products were analyzed by high pressure size exclusion chromatography (HP-SEC), dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), micro-flow imaging (MFI) and second derivative ultraviolet (UV) spectroscopy. RESULTS: Ten out of twenty-one stressed product samples (47.6%) showed increased particle numbers in the submicron and micron size range when compared to controls. For each product, DLS, MFI and NTA detected an increase in particle level in at least one stressed syringe (both continuous freezing and freeze-thaw), whereas HP-SEC and UV spectroscopy showed no differences between stressed and non-stressed products. CONCLUSION: TNF-α inhibitors are relatively resistant to freezing temperatures similar to storage conditions previously observed in patients' homes. However, almost half of the stressed product samples showed formation of particles in the submicron and micron size range.

Disease burden of knee osteoarthritis patients with a joint replacement compared to matched controls: a population-based analysis of a Dutch medical claims database.

OBJECTIVE: On a population level, the incidence of knee prostheses (KPs) has increased, but excess health care costs per patient, compared to matched controls without a KP, in the years surrounding these procedures and their determinants are largely unknown. We therefore aimed to provide estimates of age- and sex-specific incidence of KPs, revision KPs, and prosthesis complications in patients with knee osteoarthritis (OA) and to determine excess health care costs in the years surrounding surgery compared with matched controls. METHODS: All KPs in OA patients in the Achmea Health Database were identified as well as up to four controls. Incidence rates of KPs, revisions, and complications from 2006 to 2013 were determined. Annual health care cost and excess costs (over matched controls) preceding, during, and after surgery were calculated and their determinants were evaluated. RESULTS: The increased incidence of KPs, revisions, and complications was strongest in younger age categories and men. The average costs per patient were relatively stable between 2006 and 2012. KP patient's annual health care costs increased towards the year of surgery. After surgery, costs decreased, but remained higher as compared to costs prior to surgery. High post-surgery costs were mainly associated with subsequent revisions or additional KPs, but costs were also higher in females, lower age categories, and lower social economic status. CONCLUSION: These results underscore the increasing burden and medical need associated with end-stage OA, especially in younger age categories. Improvement of guidelines tailored to individual patient groups aimed at avoiding complications and revisions is required to counteract this increasing burden.

Intradermal influenza vaccination in immunocompromized patients is immunogenic and feasible.

BACKGROUND: Many strategies, including intradermal vaccination, have been tested to augment antibody responses upon vaccination. This strategy has not been evaluated in different groups of immunocompromized patients. We conducted a prospective, randomized study to compare the humoral response upon standard intramuscular influenza vaccination with the response upon reduced-dose intradermal vaccination in patients treated with anti-tumor necrosis factor (TNF)-alpha, human immunodeficiency virus (HIV)-infected patients, hematologic stem cell transplantation (HSCT) patients, and healthy controls. METHODS: In total 156 immunocompromized patients and 41 healthy controls were randomized to receive either 0.5mL of the 2005/2006 trivalent influenza vaccine intramuscular or 0.1mL intradermal. Humoral responses, determined by hemagglutination inhibition assay, were measured before and 28 days postvaccination. Geometric mean titers (GMTs) and protection rates (PRs) are reported as primary outcomes, adverse events as a secondary outcome. RESULTS: Reduced-dose intradermal vaccination leads to similar GMTs and PRs, within all tested groups, compared to the standard intramuscular vaccination. Healthy controls yielded significantly better GMTs and PRs than immunocompromized patients. Local skin reactions after intradermal vaccination occurred less frequent and were milder in immunocompromized patients than in healthy subjects and were predictive for a positive vaccination outcome for individual subjects. CONCLUSIONS: Intradermal influenza vaccination is a feasible alternative for standard intramuscular vaccination in several groups of immunocompromized patients, including those treated with anti-TNF, HIV-infected patients and HSCT patients. The occurrence of a local skin reaction after intradermal vaccination is predictive of a response to at least one of the vaccine antigens.

Sustained effect after lowering high-dose infliximab in patients with rheumatoid arthritis: a prospective dose titration study.

OBJECTIVES: In clinical trials only a small subset of patients with rheumatoid arthritis (RA) benefits from higher than standard dose of infliximab (>3 mg/kg/8 weeks). However, dose escalation of infliximab is frequently applied in clinical practice. Individual adjustment of infliximab treatment based on actual disease activity, instead of subjective clinical judgement, could prevent possible unwarranted dose escalation. METHODS: The infliximab dose of all patients with RA treated at our centre was decreased from 5 mg/kg to 3 mg/kg, leaving dosing intervals unaltered. Subsequently patients were followed for at least three infusions. At every visit, 28-joint Disease Activity Score (DAS28), infliximab serum trough levels and anti-infliximab antibody levels were assessed. Inversed European League Against Rheumatism (EULAR) criteria (flare criteria) were used as the endpoint. RESULTS: A total of 18 patients were included in the study. Mean (SD) DAS28 scores before dose reduction and after first and second low dose were 3.2 (1.2), 3.2 (1.8) and 3.3 (1.2), respectively (values not significant). One patient (6%, 95% CI 0% to 17%) developed a persistent flare that subsided after increasing infliximab doses and one patient stopped infliximab because of a lupus-like reaction. In all other patients (n=16) lowering infliximab resulted in unaltered disease activity. Infliximab levels showed that most patients had either low- (<1 mg/litre) or high (>5 mg/litre) serum trough levels. Anti-infliximab antibodies were detected in four patients. CONCLUSION: Infliximab dosages of 5 mg/kg can be lowered in the majority of patients with RA using DAS28-guided dose titration without increase of disease activity. Lowering the dose of infliximab should be considered in every patient receiving higher doses infliximab.
